Unbranded 50 ft. Mini Split Line Set 1/4"& 1/2"O.D Copper Pipes Tubing and Triple-Layer Insulation for Mini Split Air Conditioning

50 ft. Copper Tube: With a length of up to 50 ft. the copper tube can easily connect indoor and outdoor units even over long distances without difficulty. High and Low Pressure Dual Pipes: Includes 1/4 in. high-pressure tubes and 1/2 in. low-pressure tubes, compatible with 12000-18000 BTU split air conditioners, specifically designed for mini-split air conditioning systems. Thickened Pure Copper Tube: Utilizes high-quality copper tubes compliant with ASTM standards, meticulously controlling the wall thickness of both high-pressure and low-pressure tubes, providing excellent toughness and hardness, eliminating the frustration of thin copper tubes easily flattening with a single fold. Three-layer Insulation Cotton: Wrapped tightly with 3 layers of insulation cotton, the copper tube sustains effective insulation while being waterproof and pressure-resistant, offering better protection for the internal copper tubes.
